I'm suggesting that having–constructing a vision of "the end of all things" (or "practically the end..."), and then living–preparing according to that vision, seems to be something human persons are wont to do, whether they are religious or areligious.

In the Christian vision, the important thing is to prepare by living a life in correspondence with the double-precept of charity, "love God, love your neighbor" ~ cf. Matthew 22:35-40, Matthew 25:31-46 and the preceding text, to the beginning of chapter 24; also Romans 2:1-11. Jesus describes "the end" in a manner that is quite frightening (earthquakes, wars, famines, lots of suffering), but it's clear that those who are well-prepared will be able to rejoice when all is said and done.
